Is there another way of applying thermal paste to the cpu than from the syringe?

Im about to change my processor and im not very optimistic about the syringe method, it might not cover all of the processor, it might go off the processor, etc..
So is there another way, something like, sticker or something, just a little block of the paste, that you could just put to the processor and don't have to worry about?

Sadly besides pre applied paste on coolers (such as the h100i) the main way is to use the syringe.
I personally use a card to spread it out for peace of mind.

First, i highly DO NOT recommend preapplying paste with a card. You see, this is impossible that a surface is perfectly planar. both your cooler and you cpu are irregular surfaces. so if you would place them one against each-other, there would be some microscopic gap. these gaps would be filled with air. air is a good heat insulator. your cpu would have local overheating issues.

preapplied paste with a card would leave some air imprisoned in your paste and thus nullifying the utility of your paste which is to not having air between cooler and cpu.

the best way is to naturally chase all air by applying a pea size of paste on the middle of you board, and then installing your cooler. By pressing with your cooler, paste will spread and chase air in the same time.

There is no technically correct way, spreading it does increase chances of getting air in, but not nearly that much. The cooler still puts pressure on the paste, still presses air out, and will cool efficiently. I have done that method on several builds, all of them run OCed with no issues. (this build went from 3.4-4GHz on a 212 EVO like that.

There are 100 different ways to do it, and only trying all of them will you find the best one.

No matter how much pressure you apply if air is stuck in the paste, it will stay there since there is no way for it to escape. All you will do is to pressurize that air into a smaller volume. I prefer not taking chances. pea and line method are the safest to avoid air since it is impossible to get air with those method.

mechanical engineer talking of his own experience with highly precise surface contact ( 0.00005 inches surface variation)

at this variation, a full contact would appear perfect, but there is always very tiny air pocket which will form since nothing is perfectly planar.
